WATER-HEATER.

SPECIFICATION forming part of Letters Patent N 0. 714,354, datedNovember 25, 1902.

Application filed March 31, 1902. Serial No. 100,696. (No model.)

Toall whom it may concern.-

Be it known that I, HOMER ANDERSON, a citizen of the United States, anda resident of Peekski11,in the county of WVestchester and State of NewYork, have invented certairi new and useful Improvements inWater-Heaters, of which the following is a specification.

This invention relates to waterheaters Whether for the purpose ofobtaining hot wato tor for washing or bathing, for heating buildings, orany other'purposes requiring hot water. It may also be used forproducingsteam. It is herein shown as applied to a gas waterheater; but it is notby any means limited to such purpose.

The objects of the invention are to combine in a heater means forobtaining the largest possible area of heating-surface in proportion tothe quantity of water carried in the heater,

.20 for applying the heat in quantity and in the most efficient mannerto obtain quick results, and for obtaining a uniform distribution ofheataround the heating-surfaces. These objects are attained by the meansset forth in 2 5 the specification and the drawings, forming a partthereof, that accompany it.

Figure l is a view of a gas water-heater,

, shown in elevation, with the jacketing partly removed, disclosing thefeatures of my invention. Fig. 2 is a plan of one-half of the bottom andthe gas-burner. Fig. 3 is a crossseotion of a heater-sectionreturn-bend. Fig. 4 represents a heater-section with one bend and partsof the central hubs broken away.

Fig. 5 shows a cross-section of a flat oval return-bend. Fig. 6represents a portion of a water-section bend. Fig. 7 is the plan of thesections shown in Figs. 1, 4, and 12 and will also apply to Fig. 10.Fig. 8 shows the crosssection of a bend through line y, Fig. 7. Fig. 9represents a portion of a section-bend. Fig. 10 represents a section, asin Fig. 4, but having bonds with a rectangular cross-section.

. Fig. 11 is a cross-sectional view through line 1 ,Fig. 10. Fig. 12represents a section made with close return-bends and Fig. 13 is acrosssection through line y, Fig. 12.

A particular feature of this invention is the heater-section a, Figs. 1,4, 7, 10, 12, which I can best describe as consisting of a number (eightare here shown) of return-bends standing vertically and radially fromcentral hubs Z) Z), the upper outlet of the bends united to one hub band the lower outlets of the bends united to the lower hub Z). Forextensive manufacture it would not be desirable to make these sectionsactually 01E hubs and bonds on account of the expense and the number ofjoints that would enter into such a construction, so I make the sectionsof cast metal, of iron, brass, copper, aluminium, or whatever may besuitable, and what I shall call the hubs and return-bends will beunderstood to be preferably one integral casta 6s The form of thereturn-bends may be'varied to suit conditions under which the sectionsare to be used. The section shown in Fig. 1 is revealed in plan in Fig.7, showing it to comprise eight bends a,having cross-sections, as shownin Fig. 8, which is taken through line 1 of Fig. 7. A flat ovalcross-section, as shown in Fig. 5, and a vertical ellipticalcrosssection, as shown in Fig. 3, have advantages for certain uses.Instead of the bends opening in the form of an acute angle, as in Fig.

4, they may be parallel open bends, as in Fig.

6 or as in Fig. 9, in which the bend is shown to have a squarecross-section. In Fig. 10 still another form of bend is shown having across-section as shown in Fig. 11.

In Fig. 12 the section is represented as made with close return-bendshaving a crosssection as in Fig. 13. The course of the water throughthis section is represented by the arrows n, and it is the same throughall the sections shown, the water entering one hub, passing around theseveral bends, and passing out of the opposite hub, the waterdistributing itself in its flow practically equally 9o threaded nipples.As many sections may be joined to make a heater as circumstances mayrequire.

In Fig. 1 for the purposes of a gas waterheater three sections are shownsupported by the water-pipe o c. A bottom flange 6, having hubs 7 and 8,is secured to the waterpipe. This bottom is perforated, as shown in Fig.2, and supports a base 5 and also the burner df. Upon this base thejacket 1 2 3 4: is sustained, and a top 10, with a pipe-outlet 11,surmounts the jacket. This base, jacketing, and top are features commonto other heaters.

The gas-burner dfis supplied in the usual manner through a pipe 6. Thisburner is adapted to the form of the heater-section, having branches finnumber equal to the retu rn-bends in the water-section,which have aninclination from a horizontal plane corresponding with that of the bendof the section, with the object of throwing the burner-flame as nearlyas practicable at a right angle to the surface of the sections. Thissecures an even supply of flame beneath each bend of the first section.The burner is shown as supported by legs 9, resting on the hub 8.

In order to increase the volume of the heating medium, I place a secondburner h between the first and second sections and supply it from thebody of the lower burner through stand-pipes g g, the lower burner andits supply being adapted for this additional requirement of gas. Tostill further augment the heating medium and to insure a volume of heatabout the hubs of the sections, I add still a third burner Z within thespace made by the opening of the returnbends in the second watersection. This burner also gets its gas-supply from the lower burner.With the two large burners h and df below the third burner it is evidentthere would be little oxygen left in the air ascending through theheater to support combustion at the burner Z. I therefore place afreshair-supply pipe m in such position that a strong draft will becreated through it and fresh air will be injected by it right over theburner Z, which will prevent its being extinguished. A like supply ofair may be conducted to the middle burner n if found necessary. Theburner Z is supplied with gas from the lower burner through the pipe 2'.

A hole 16 through the jacketing is provided with a closure that may beeasily opened, and through this hole the burners may be ignited, theburner Z first, when its flame will ignite the gas rising from theburner 7t and that in turn igniting the gas arising from the lowerburner. It will thus be seen that if desirable I may place a burner orother adaptable heating medium contiguous to each water-section, eitherbetween the sections or within the bends of the sections, or both.

In order to prevent the products of combustion being drawn to one sideof the heater by the draft through the pipe-outlet 11, I place abaflle-plate 25 within the top of the jacketing with an opening only inthe center. This will tend to draw the heated air about the center ofthe water-sections, while the form of the water-sections will have atendency to deflect the hot air away from their centers.

In the supply of gas to more than one burner, as herein described, I donot wish to be limited to the manner shown of supplying each burner froma single one, as a reservoir. It is plainly practicable to give eachburner an independent supply and provide that one or more burners may belighted, according to the requirements for hot water. It will be plainalso that the gas-burners shown may be displaced for naphtha or otherfluid burners, and the sections are well adapted for the employment ofelectric heaters, and I desire that my claims shall include such meansof heating.

I claim- 1. In a water-heating device a heating-section composed ofhollow hubs and a series of return-bends radiating from said hubs andconstituting communicating tubes between the hubs, whereby the waterflows freely from one hub to the other through said returnbends,substantially as described.

The combination substantially as herein shown of a heater composed ofsections consisting of open return-bends united radially to central hubsin the manner described, a burner under the bottom section adapted toproject its flames at a right angle to the heating-surface of thesection, a burner between the first and second sections supplied withgas from the lower burner, a burner, likewise supplied with gas from thelower burner, within the bends of the second section, and afresh-air-supply pipe to the top burner.

3. The combination substantially as herein shown, of a heater composedof sections consisting of open return-bends united radially to centralhubs in the manner set forth, a burner under the bottom section adaptedto project its flames at a right angle to the heating-surface of thesection, a burner between the first and second sections supplied withgas from the lower burner, a burner within the bends of the secondsection likewise supplied with gas from the lower burner, a freshairinlet contiguous to the top burner, and an opening in the jacketing tofacilitate the lighting of the top burner.
